Abstract
Description
Technical Field
[0001] The present application relates to the technical field of environmental protection water treatment, and in particular to a sewage treatment device. Background Art
[0002] At present, sewage treatment devices have been widely used in sewage treatment. However, the horizontal flow sedimentation tanks used in general sewage treatment devices are prone to short-flow phenomenon, resulting in actual reaction time and sedimentation time being far lower than the calculated values, and the treatment effect is poor.
[0003] In order to solve this problem, it is usually necessary to set up multiple reaction zones and retaining walls in the reaction sedimentation tank, which makes the structure complicated, expensive, and difficult to maintain. Especially for renovation projects, the conditions for adding retaining walls and reaction zones are often not available on site.
[0004] Therefore, it is necessary to study and improve the above structure and provide a sewage treatment device in order to achieve a more practical purpose. Utility Model Content
[0005] In view of the technical problems existing in the background technology, the present application provides a sewage treatment device to solve the problem in the prior art that multiple reaction zones and retaining walls need to be set in the reaction sedimentation tank, resulting in complex structure, high cost and difficult maintenance.
[0006] The present application provides a sewage treatment device, comprising:
[0007] A reaction pool, wherein a first guide groove is installed in the reaction pool, and the wall surface of the reaction pool and the first guide groove form a first guide channel for guiding the liquid in the lower part of the reaction pool to the upper part;
[0008] A sedimentation tank is provided with a second guide groove, the wall of the sedimentation tank and the second guide groove form a second guide channel, the upper part of the second guide channel is connected with the upper part of the first guide channel, and the second guide channel is used to guide the upper liquid in the first guide channel to the lower part of the sedimentation tank.
[0009] In the technical solution of the embodiment of the present application, a first guide channel is formed by installing a first guide groove in the reaction tank, and a second guide groove and a second guide channel are installed in the sedimentation tank, and the upper part of the first guide channel is connected to the upper part of the second guide channel. Therefore, the function of the traditional reaction sedimentation tank can be realized by only setting a primary reaction tank and a sedimentation tank, avoiding the short-circuit phenomenon between the reaction zone and the sedimentation zone.
[0010] The influent rises from the first guide channel of the reaction tank and flows out from the lower part of the second guide channel after passing through the upper part of the second guide channel of the sedimentation tank, which increases the feeding reaction time of the reaction tank and reduces the height of the outflow end of the sedimentation tank, thereby improving the reaction effect and sedimentation effect.
[0011] That is, by adding a guide trough, short-circuiting can be avoided and there is no need to add additional reaction zones and retaining walls. The reaction and sedimentation effects of a traditional reaction sedimentation tank using double reaction zones plus retaining walls can be achieved. This method has the advantages of simple structure, low cost and low maintenance difficulty, and is easy to promote and use in renovation projects on site that do not have the ability to add retaining walls and reaction zones.
[0012] In some embodiments, the reaction tank is disposed on one side of the sedimentation tank, and a flow hole connected to the sedimentation tank is provided on the reaction tank, and the upper part of the second guide channel and the upper part of the first guide channel are connected through the flow hole.
[0013] In this embodiment, by arranging the reaction tank and the sedimentation tank adjacent to each other, it is only necessary to open a hole in the partition wall to form a flow hole connecting the upper part of the second guide channel and the upper part of the first guide channel. For renovation projects that do not have the ability to add retaining walls and reaction areas on site, it has the advantage of low construction and renovation difficulty.
[0014] In some embodiments, the first guide groove and the second guide groove are both arranged in a vertical direction, and a fiberglass anti-corrosion layer is disposed on the inner sides of the first guide groove and the second guide groove.
[0015] In this embodiment, by vertically arranging the first guide groove and the second guide groove, the diversion resistance during use can be reduced, and the fiberglass anti-corrosion layer arranged on the inner side of the first guide groove and the second guide groove has the advantages of a smooth surface and strong corrosion resistance, and is not easy to adhere to sediment during use.
[0016] In some embodiments, a guide plate for changing the flow direction of water is installed at the lower part of the second guide groove, and the angle between the guide plate and the horizontal direction is 45° to 60°.
[0017] In this embodiment, by installing a guide plate at the bottom of the second guide trough and controlling the angle between the guide plate and the horizontal direction to be between 45° and 60°, the outflow direction of the lower part of the second guide trough can be switched from a vertical direction to a horizontal direction, thereby preventing the water flow from directly impacting the bottom wall of the sedimentation tank and causing the sludge to float.
[0018] In some embodiments, the distance from the bottom end of the first guide channel to the bottom wall of the reaction tank is 500 mm to 1000 mm.
[0019] In this embodiment, by controlling the distance from the bottom end of the first guide groove to the bottom wall of the reaction tank during installation, the reaction time of the material in the reaction tank diffusing downward can be guaranteed, while the diversion effect can be guaranteed to avoid a large amount of particulate matter deposited on the bottom wall of the reaction tank.
[0020] In some embodiments, the distance from the bottom end of the second guide channel to the bottom wall of the sedimentation tank is 1000 mm to 2000 mm.
[0021] In this embodiment, by controlling the distance from the bottom end of the second guide trough to the bottom wall of the sedimentation tank during installation, the sedimentation effect in the sedimentation tank can be ensured, and the outflow of the second guide trough can be prevented from disturbing the clear liquid area formed in the upper layer of the sedimentation tank, and the outflow impact of the second guide trough can be prevented from causing a large amount of sludge at the bottom of the sedimentation tank to float up.
[0022] In some embodiments, the first guide groove and the second guide groove each include a plurality of U-shaped groove segments, and the plurality of U-shaped groove segments are sequentially spliced to form the first guide groove and the second guide groove, respectively.
[0023] In this embodiment, the first guide trough in the reaction tank and the second guide trough in the sedimentation tank are installed by adopting a segmented splicing installation method, which reduces the difficulty of installation and facilitates maintenance and use.
[0024] In some embodiments, the left and right sides of the first guide groove and the second guide groove are both provided with wing edges, the wing edges are provided with mounting holes, and the outer walls of the first guide groove and the second guide groove are both provided with U-shaped reinforcement ribs extending to the wing edges.
[0025] In this embodiment, by providing wings on both sides of the guide groove and opening mounting holes on the wing edges, the guide groove can be conveniently attached to the pool wall through the wing edges and fixedly installed by fasteners. At the same time, the U-shaped reinforcement ribs provided on the outer wall of the guide groove extend to the surface of the wing edges, which can enhance the strength and rigidity of the guide groove.
[0026] In some embodiments, steel belts are provided on the outer walls of the first guide groove and the second guide groove, and both ends of the steel belts are fixedly installed by fasteners to clamp the first guide groove and the second guide groove on the wall surfaces of the reaction tank and the sedimentation tank respectively.
[0027] In this embodiment, the guide groove is clamped to the pool wall by steel belts fixed at both ends, which can further fix the guide groove, increase the structural strength of the guide groove, and prevent the guide groove from being deformed due to pressure and temperature during use to a certain extent.
[0028] In some embodiments, the reaction tank is equipped with a stirrer with a stirring paddle extending into the reaction tank, and the sedimentation tank is equipped with a sludge pump connected to the bottom of the sedimentation tank.
[0029] In this embodiment, by using the stirring paddle on the mixer to stir the reaction tank, the feed and sewage can be fully mixed and reacted, while preventing the particles produced by the reaction from settling in the reaction tank. In addition, the installed sludge pump can discharge the sludge settled at the bottom of the sedimentation tank to ensure the continuous operation of the sedimentation tank.

[0049] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the water flow path of the reaction sedimentation tank provided by the prior art, Figure 2 A top view of the structure of the reaction sedimentation tank provided by the prior art. When the reaction sedimentation tank is in use, the water flows in from the upper part of the first reaction zone 1, passes through the wall from the bottom of the first reaction zone 1 and flows into the bottom of the second reaction zone 2, and then passes through the wall from the top of the second reaction zone 2 and flows into the upper part of the water inlet channel of the sedimentation zone 3, and passes through the flow channel formed by the retaining wall 4, and the water flows into the sedimentation zone 3 from the bottom of the retaining wall. That is, in order to ensure that the materials react fully, the reaction sedimentation tank of the prior art usually sets two or more reaction zones and cooperates with retaining walls to avoid short-circuit phenomenon, which makes the structure complicated, expensive, and difficult to maintain. Especially for renovation projects, the conditions for adding retaining walls and reaction zones are often not available on site.
[0050] In order to solve the technical problems in the prior art that multiple reaction zones and retaining walls need to be set in a reaction sedimentation tank, resulting in complex structure, high cost and difficult maintenance, the present application provides a sewage treatment device, wherein a first diversion channel is formed by installing a first diversion trough in the reaction tank, and a second diversion channel is formed by installing a second diversion trough in the sedimentation tank, and the upper part of the first diversion channel is connected to the upper part of the second diversion channel.
[0051] Therefore, the function of a reaction sedimentation tank can be realized by setting up only a primary reaction tank in combination with a sedimentation tank, which can avoid short-circuiting and does not require additional reaction areas and retaining walls. It has the advantages of simple structure, low cost and low maintenance difficulty, and is easy to promote and use in renovation projects that do not have the ability to add retaining walls and reaction areas on site.
[0052] Please refer to Figure 3 , is a schematic diagram of the structure of a sewage treatment device provided in an embodiment of the present application. The embodiment of the present application provides a sewage treatment device, including:
[0053] A reaction tank 10, wherein a first guide groove 11 is installed in the reaction tank 10, and a wall surface of the reaction tank 10 and the first guide groove 11 form a first guide channel 12 for guiding liquid in a lower part of the reaction tank 10 to an upper part;
[0054] The sedimentation tank 20 has a second guide groove 21 installed therein. The wall of the sedimentation tank 20 and the second guide groove 21 form a second guide channel 22. The upper part of the second guide channel 22 is connected to the upper part of the first guide channel 12. The second guide channel 22 is used to guide the upper liquid in the first guide channel 12 to the lower part of the sedimentation tank 20.
[0055] The sewage treatment device of the embodiment of the present application forms a first guide channel 12 by installing a first guide groove 11 in the reaction tank 10 and cooperating with the tank wall, and forms a second guide channel 22 by installing a second guide groove 21 in the sedimentation tank 20 and cooperating with the tank wall, and the upper part of the first guide channel 12 is connected to the upper part of the second guide channel 22.
[0056] like Figures 3 to 5 As shown, when in use, the incoming water rises from the bottom end of the first guide channel 12 of the reaction tank 10 and flows out from the lower part of the second guide channel 22 after passing through the upper part of the second guide channel 22 of the sedimentation area. The flow path from the reaction tank 10 to the sedimentation tank 20 becomes longer, which can avoid the short-flow phenomenon that the incoming water in the reaction tank 10 directly overflows into the sedimentation tank 20. The feed in the reaction tank 10 can fully sink and react, ensuring that the material in the reaction tank 10 can fully react, so that the water flow residence time is the same as the actual reaction time, ensuring the reaction effect.
[0057] At the same time, after the reaction, the sewage flows out from the lower part of the second guide channel 22 in the sedimentation tank 20, the height of the outflow end is reduced, and the distance between the particles formed by the reaction and the bottom wall of the sedimentation tank 20 becomes smaller. The particles can use their own weight to settle to the bottom wall of the sedimentation tank 20 quickly, which does not affect the continuous discharge of the upper clear liquid of the sedimentation tank 20, and the treatment effect of the sedimentation tank 20 is improved.
[0058] That is, the sewage treatment device of the present application can reduce one reaction zone and one retaining wall by using the diversion trough, which can reduce construction investment and shorten the construction period in the construction project. For the renovation project, for the original one reaction tank and sedimentation tank, the design of the diversion trough will be an effective solution.
[0059] Further, in the embodiments of the present application, Figure 3 and Figure 4 As shown, the reaction tank 10 is arranged on one side of the sedimentation tank 20, and a flow hole 30 connected to the sedimentation tank 20 is provided on the reaction tank 10, and the upper part of the second guide channel 22 and the upper part of the first guide channel 12 are connected through the flow hole 30. Specifically, in this embodiment, the reaction tank 10 and the sedimentation tank 20 are arranged adjacent to each other, and the flow hole 30 is provided on the partition wall between the reaction tank 10 and the sedimentation tank 20, and the flow hole 30 is connected to the upper part of the guide channels on both sides, which has the advantage of low construction and renovation difficulty for the renovation project that does not have the ability to add a retaining wall and a reaction zone on site.
[0060] Further, in the embodiments of the present application, Figure 4 As shown, the first guide groove 11 and the second guide groove 21 are arranged in the vertical direction, and the inner sides of the first guide groove 11 and the second guide groove 21 are provided with a glass fiber reinforced plastic anti-corrosion layer. Specifically, in this embodiment, the first guide groove 11 and the second guide groove 21 are respectively installed vertically on the partition wall between the reaction tank 10 and the sedimentation tank 20 and are symmetrical in left and right positions, which can reduce resistance during diversion, and the glass fiber reinforced plastic anti-corrosion layer provided on the inner sides of the first guide groove 11 and the second guide groove 21 has the advantages of smooth surface and strong corrosion resistance, and is not easy to adhere to sediment during use. For example, the first guide groove 11 and the second guide groove 21 can be formed by pressing glass fiber reinforced plastic.
[0061] Further, in the embodiments of the present application, Figure 4 As shown, a guide plate 23 for changing the flow direction of water is installed at the lower part of the second guide groove 21, and the angle between the guide plate 23 and the horizontal direction is 45° to 60°. Specifically, in this embodiment, the guide plate 23 is fixedly installed at the lower opening of the second guide groove 21, and an opening facing the inclined surface of the guide plate 23 is opened on the side wall of the second guide groove 21. Under the action of the guide plate 23, the water flow switches direction and flows out from the opening. The installation angle between the guide plate 23 and the horizontal direction is controlled at 45° to 60°, which can prevent the bottom sludge from floating up due to the impact of the water flow, and at the same time, it can prevent the accumulation of sludge on the guide plate 23.
[0062] Further, in the embodiments of the present application, Figure 4As shown, the distance from the bottom end of the first guide groove 11 to the bottom wall of the reaction tank 10 is 500mm to 1000mm. Specifically, by controlling the distance from the bottom end of the first guide groove 11 to the bottom wall of the reaction tank 10 during installation, the reaction time of the feed in the reaction tank 10 to diffuse downward can be guaranteed, while ensuring the diversion effect and avoiding a large amount of particulate matter deposited on the bottom wall of the reaction tank 10. If the distance from the bottom end of the first guide groove 11 to the bottom wall of the reaction tank 10 is too small, it is easy to cause the particulate matter generated by the reaction to be directly deposited on the bottom wall of the reaction tank 10. If the distance from the bottom end of the first guide groove 11 to the bottom wall of the reaction tank 10 is too large, it is easy to cause the feed in the reaction tank 10 to be diverted to the sedimentation tank 20 before it has time to fully react.
[0063] Further, in the embodiments of the present application, Figure 4 As shown, the distance from the bottom end of the second guide trough 21 to the bottom wall of the sedimentation tank 20 is 1000 mm to 2000 mm. Specifically, by controlling the distance from the bottom end of the second guide trough 21 to the bottom wall of the sedimentation tank 20 during installation, the sedimentation effect in the sedimentation tank 20 can be ensured, and the outflow of the second guide trough 21 can be prevented from disturbing the clear liquid area formed on the upper layer of the sedimentation tank 20, and the outflow impact of the second guide trough 21 can be prevented from causing a large amount of sludge at the bottom of the sedimentation tank 20 to float up. If the distance from the bottom end of the second guide trough 21 to the bottom wall of the sedimentation tank 20 is too small, the outflow of the second guide trough 21 impacts the sludge on the bottom wall of the sedimentation tank 20 and affects the sedimentation effect. If the distance from the bottom end of the second guide trough 21 to the bottom wall of the sedimentation tank 20 is large, the outflow of the second guide trough 21 is easy to muddy the clear liquid area and affect the discharge of the clear liquid.
[0064] Further, in the embodiments of the present application, Figure 3 As shown, the first guide groove 11 and the second guide groove 21 each include a plurality of U-shaped groove segments, and the plurality of U-shaped groove segments are sequentially spliced to form the first guide groove 11 and the second guide groove 21. Specifically, the first guide groove 11 in the reaction tank 10 and the second guide groove 21 in the sedimentation tank 20 are installed by adopting a segmented splicing installation method, so that the construction is flexible, and guide grooves of different lengths can be spliced and installed according to actual needs, which reduces the difficulty of installation and is easy to maintain and use.
[0065] Further, in the embodiments of the present application, Figure 6 As shown, the left and right sides of the first guide groove 11 and the second guide groove 21 are both provided with wing edges 40, and mounting holes are provided on the wing edges 40. The outer walls of the first guide groove 11 and the second guide groove 21 are both provided with U-shaped reinforcing ribs 50 extending to the wing edges 40. Specifically, the guide grooves are integrally formed with wing edges 40 on both sides and mounting holes are provided on the wing edges 40. During installation, the wing edges 40 are attached to the pool wall and expansion bolts are installed using the mounting holes, thereby fixing the guide grooves to the pool wall. At the same time, the outer walls of the guide grooves are integrally formed with U-shaped reinforcing ribs 50 extending to the surface of the wing edges 40, which can enhance the strength and rigidity of the guide grooves.
[0066] Further, in the embodiments of the present application, Figure 6 As shown, steel belts 60 are provided on the outer walls of the first guide groove 11 and the second guide groove 21, and both ends of the steel belts 60 are fixedly installed by fasteners to respectively hold the first guide groove 11 and the second guide groove 21 tightly on the wall surfaces of the reaction tank 10 and the sedimentation tank 20. Specifically, when the guide groove is fixedly installed on the pool wall, the steel belt 60 can be further installed to hold the guide groove tightly on the pool wall to increase the structural strength of the guide groove and avoid excessive deformation of the guide groove due to pressure and temperature during use.
[0067] Further, in the embodiments of the present application, Figure 6 As shown, the reaction tank 10 is equipped with a stirrer (not shown in the figure) whose stirring paddle extends into the reaction tank 10, and the sedimentation tank 20 is equipped with a sludge pump (not shown in the figure) connected to the bottom of the sedimentation tank 20. Specifically, by using the stirring paddle on the stirrer to stir the reaction tank 10, the feed and sewage can be fully mixed and reacted, and the generated particles can be prevented from settling in the reaction tank 10. In addition, the installed sludge pump can discharge the sludge settled at the bottom of the sedimentation tank 20 to ensure that the sedimentation tank 20 continues to work.
[0068] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
